Question: theoretically, can basically anyone make money on sites like xtube?

So this is a question spurned by a research paper i did a year back and thought of recently. Most porn is physically fit guys, but guys who aren't that fit seem to get more views in the free sections on sites such as xtube. Not to mention from guys like Adam Killian to Zack Randall, those fit types come a dime a dozen. So here's the question, say a "chub" decided to go from free vids to making an amateur account. Theoretically, they too could make a meager amount couldn't they? Opinions welcome but you should at least be "legal age" if you're gonna answer this one :P
